Abstract

A blower may include a motor; a centrifugal fan configured to rotate with rotation of the motor; a casing configured to guide air from a suction port to a discharge port; a trigger configured to be pressed; and a control board configured to control rotation of the motor. The control board may include a normal mode and a low speed mode. In the normal mode, the control board may be configured to adjust a rotation speed of the motor in accordance with a degree by which the trigger is pressed. In the low speed mode, the control board may be configured to adjust the rotation speed of the motor to a target rotation speed, wherein the target rotation speed is lower than a maximum rotation speed of the motor that is achieved when the degree by which the trigger is pressed is a maximum degree in the normal mode.
